Effective COVID Vaccine unlikely soon - Moderna vaccine caused "adverse" reactions in roughly 50% of patients - Evidence Shows COVID-19 Antibodies Disappear Not Long After Infection

"Following trial results released yesterday showing Moderna's vaccine candidate might not be safe for human consumption - apparently, the candidate caused "adverse" reactions in roughly 50% of patients who participated in a recent study - the dozens of companies, universities and governments working on COVID-19 vaccine candidates just received another piece of disheartening news: A growing body of evidence gleaned from research into the virus suggests that antibodies may not offer protection for more than 2-3 months, for many people.



Now, a study produced by researchers at King’s College London is showing recovered patients antibodies declined significantly within months of infection, raising the critical question of whether a vaccine could ever provide lasting protection. Moderna's vaccine candidate has shown the capacity to produce antibodies in test subjects, but it's still unclear exactly how much protection this might provide."
